Former world champion Miguel Cotto, looking to reverse the first two-fight losing streak of his legendary career, announced two significant moves via Twitter on Saturday.

Cotto wrote that he had hired Freddie Roach to train him, replacing Pedro Diaz, and that he would fight on Oct. 5 on a Top Rank card. There has been much speculation that Cotto would fight Carlos Molina, but he didn't mention an opponent and Top Rank president Todd duBoef could not be reached for comment.

Cotto began his career with Top Rank, which signed him in 2000 off the Puerto Rican Olympic team. He became one of the sport's biggest stars and won world titles at 140, 147 and 154 pounds.

But in January 2012, he left Top Rank to sign with Golden Boy in order to take a May 5, 2012, bout in Las Vegas against Floyd Mayweather Jr. Cotto lost a unanimous decision to Mayweather, then fought once more for Golden Boy. He lost another unanimous decision to Austin Trout in a fight that did a big rating on Showtime.
